Aqua One Betta Filter Service Kit

Fit a new Aqua One 1c and the Aqua One 102c when you receive the kit. Once per month after this replace the 1c and gently rinse the Aqua One 102c in a little aquarium water (it doesnt have to be pristine) to preserve the helpful filtration bacteria that grow on the ceramic granules. The sponge block may be rinsed in the same way.
